PF940SC Polymer Frame for Compact Builds

When you require a reliable foundation for your next compact pistol build, the PF940SC frame offers the structural integrity and design precision you demand. This 80 percent frame is machined from high-quality polymer and engineered to accept a wide range of aftermarket components, making it a preferred choice for builders who value control over every aspect of their firearm. The PF940SC is not a finished firearm; it is a component that requires further machining, assembly, and compliance with all applicable laws. For experienced builders, this frame represents a direct path to a custom compact handgun tailored to your specifications.

Overview

The PF940SC is a compact-size polymer frame designed for use with compatible internal parts kits and slides. It features reinforced front locking block rails and a rear rail module molded directly into the polymer structure, providing a stable platform for cycling and accuracy. The frame geometry follows the SC (subcompact) pattern, offering a shorter grip length and slide profile while maintaining a full-size control interface. This frame is intended for builders with the necessary tools, knowledge, and legal standing to complete a firearm for personal use. It is not a ready-to-fire product and must be finished in compliance with federal, state, and local regulations.

Features & Specs

• Frame material: High-impact, UV-resistant polymer with textured grip surfaces for positive control under varied conditions.
• Rail system: Integrated front locking block rails and rear rail module, both precision-molded to accept standard compact trigger housings and locking blocks.
• Compatibility: Accepts compact-size slides, barrels, and internal parts kits designed for the PF940SC platform. Magazine release is pre-installed with an ambidextrous configuration.

The PF940SC frame includes a stainless steel locking block and rear rail module set, both of which are installed during the finishing process. These components are essential for proper slide-to-frame fit and reliable cycling. The frame is drilled for standard compact takedown pins and uses a standard compact recoil spring assembly. All critical dimensions follow the original SC pattern, ensuring broad compatibility with aftermarket support parts.

Who It’s For

The PF940SC is designed for the experienced firearm builder who understands the legal and technical requirements of completing an unfinished frame. This product is not intended for first-time builders or individuals unfamiliar with fire control group installation, slide fitting, and function testing. It is appropriate for those who want to build a compact carry or range pistol with a custom combination of components, including aftermarket triggers, barrels, and slide optics. The PF940SC is also suitable for builders who prefer to finish a frame at home using standard shop tools, provided they comply with all applicable laws regarding firearm manufacture for personal use.

• Builders with prior experience finishing polymer frames or 80% lowers.
• Individuals who want a compact platform compatible with a wide range of compact slides, barrels, and internal parts.
• Those who understand that this frame must be completed and serialized if required by law, and who accept full responsibility for compliance.
